DANIEL MAHONEY, OF BONANZA, COLORADO.

BOILER-CLEANER.

Specification of Letters Patent.

Application filed. June 5, 1907.

Patented April 13, 1909.

Serial No. 377,410.

T 0 all whom it may concern:

Be it known that I, DANIEL I\IAHONEY, a citizen of the United States, residing at B0- nanza, in the county of Saguache, State of Colorado, have invented certain new and useful Improvements in Boiler-Cleaners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in boiler cleaners and more particularly it comprises a wire brush de signed to be reciprocated manually along the bottom of the boiler to force mud and scaly refuse into the back part of the boiler when blowing off, the object being to provide a novel construction, combination and arrangement of parts.

The details of the invention will appear in the course of the following description, in which reference is bad to the accompanying drawings forming a part of this specification, like characters of reference designating similar parts throughout the several views, wherein Figure 1 shows a central longitudinal sec tion of an ordinary steam boiler and the present invention applied thereto. Fig. 2 is an elevation looking at the inner side of a closure plate for the boiler manhole. Fig. 3 is a front elevation of the brush. Fig. 4 is a side elevation thereof. Fig. 5 is an elevation looking at the inner side of a slightly modified embodiment of closure plate. Fig. 6 is a detailed view illustrating a modified form of brush handle formed with flat faces to cooperate with the plate illustrated in Fig. 5.

Referring specifically to the accompanying drawings, the numeral 1 designates a conventional steam boiler, 2 its manhole and 3 its closure plate. The plate 3 is formed with a centralopening 4 and with a boss 5 on its outer face, the latter having a recess 6 concentric to said opening. A packing gland 7 is disposed within the recess 6, and is constructed with laterally projecting flanges 8 which are bolted to the boss 5.

The boiler cleaner per se is constituted of a head 9 carrying stiff wire strands 10 which are of such proportions that their lower ends conjointly form an arc of a circle in conformity to the curvature of the boiler. The head 9 carries a handle section 11 projecting therefrom at a substantial right angle and formed with a threaded end 12 for engagement in a socket 13, provided in the end of an elongated handle section 14, the latter being constituted with a hand grip 15. The plate 3 is constructed, in the preferred embodiment of the invention with projecting lugs 16 arranged slightly above the opening 4, and formed to engage the head 9 to prevent rotation there of, when the section 14 is being threaded upon or unthreaded from the section 11. hen the device is not in use, the section 14 is removed and a cap 17 is threaded on the end 12, the cap 17 serving as a thread protector and also as a means for preventing displacement of the section 11 from the plate 3.

In the embodiment of the invention illustrated in Figs. 5 and 6, the section 11 is formed with flat-sides 18, and the plate 3 is formed with lugs 16 arranged above and below the opening 4 for engagement with the flat sides 18, the function being the same as previously set forth.

In use, the sections 11 and 14 are articulated and the brush moved manually, the handle sections working through the gland 7, which is employed to prevent the escape of steam.

The boiler cleaner embodied in the present invention is simple in construction, inexpensive to manufacture and practical and efficient in use.

From the foregoing description it will be seen that simple and efficient means are provided for accomplishing the objects of the invention, but while the elements herein shown and described are well adapted to serve the functions set forth, it is obvious that various minor changes may be made in the proportions, shape and arrangement of the several parts without departing from the spirit and scope of the invention as defined in the appended claim.

What is claimed is: a

The combination of a boiler having a manhole, of a centrally perforated closure plate mounted in said man-hole, a boss formed on one face of said plate, a rod slidable through the perforation in said plate, a packing gland surrounding the rod and mounted in the boss, a cross-head detachably connected to one end of said rod, a plurality of relatively stiff strands of Wire carried by the cross head, and lugs projecting from the other face of said closure plate and adapted to engage said crolss head for detaching the latter from the ror.
